Be it known that 1, JAMES M. DE \VITT, of

My invention relates to preventing the accidental movement of cars onside tracks and arresting the backward movement of detach ed cars whileascending a grade.

The spiral springF isattached at one end to pawl D at E and at the other end to lower edge ofguard G.
